Before starting this procedure, you must disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide or follow the abbreviated instructions below to disable Auto Boot.

Power on your Mac and launch Terminal.

Copy and paste the following command (or type it exactly) into Terminal:

Wedge your fingers between the upper case and the lower case, starting from the rear of the MacBook between the hinges.

Lift the lower case only slightly to avoid damaging the cables that connect the lower case to the upper case.

Keeping a firm grip, lift steadily until the lower case separates slightly from the upper case.

You may experience a lot of resistance when lifting the lower case. If necessary, slide an opening pick or other ESD-safe pry tool down the side edges of the lower case to pop the two hidden retaining clips free.

During reassembly, to re-engage the clips, press firmly near both side edges of the lower case (near where the pick is inserted in the third image) until you hear the clips snap into place.

Disconnect the display cable by gently pulling it straight out of its connector.

Immediately close the retaining flap.

The flap must remain closed when the cable is reinserted during reassembly. Line up the cable with the gold contacts facing down, and gently slide it into the closed connector. Take care not to crimp or damage the cable. When fully inserted, the indentations on the sides should not be visible.

There's very little clearance when removing and installing the USB-C port. If there's not enough room, don't force it. Try removing the display hinge screws and moving the hinges for additional clearance, if necessary.

Take care not to lose the small retaining bracket located under the right screw. If it comes loose, note the orientation shown here for reassembly. The small tab on the outer left edge should be hooked under the perforated metal shield.
